Ender 3 V2 Neo: first ´rinting, printer printing the "wind", PLA does not come out

Below is the result of my first print using Ender 3 V2 Neo.

This is a new, unused printer. After assembling it, I watched the official Creality video to level it up.: https://www.youtube.com/watch?v=NJj-QtXUsps

3 minutes after printing starts, I changed the print speed to 500/1000.
I followed the printing until about 33%, then I went to take a shower, when I came back it was at 85%, and the printer was printing “wind”, no PLA was coming out of its nozzle. The problem persisted when I tried to print a new part: https://www.youtube.com/watch?v=SI3SbmGeeK0

I’m a complete newbie and I don’t know where I went wrong.
